Coloring is a great way to relax and focus, but it can be hard to find the right pen.
Some pens bleed through the page or dry out quickly. Other pens don’t have enough ink for complex coloring pages. Still, other pens leave your hands stained with color after you’re done drawing.
We’ve made a list of the best pens for colouring. Use them in your favorite adult coloring books, on printed pages, your own drawn artwork, and more. The best coloring pens are the ones that make your art pop off the page with vivid color. These are our top pics for the best coloring pens and markers.
Glossary of terms for the types of pens for coloring:
- Fineliners – Very fine-tipped pens, usually 0.3-0.4mm. Used for very small spaces not for coloring large spaces on a page. Popular brands: Staedtler Triplus, Stabilo.
- Water-based pens- This type of ink does not bleed through most papers and is ideal for double-sided books (always check first as paper quality varies). The ink in water-based pens doesn’t blend as well and can look streaky. Water-based pens are cheaper than other inks. Popular brands: Staedtler Triplus, Tombow, Crayola Supertips.
- Alcohol-based pens- This ink will bleed heavily through most papers but has excellent blending capability and colour range. Crafters use these types of pens as they give seamless color, blend really well, and don’t streak. Popular brands: Spectrum Noir, Promarker, Copic, Touch, Chameleon
- Gel pens- Gel ink. Lays down thickly on the paper and has to be left to dry otherwise it may have some smearing. There are so many different types of gel ink and they are widely available. Popular brands: Uniball Signo, Sakura Gelly Roll.
- Open Stock pens- This means buying a single pen on its own, rather than in a set. If you are unsure of a type of pen, you can try a few open stock pens (especially the more expensive pen bands) before purchasing a whole set.
What are the Best Pens for Colouring?
The list below will tell you about some of the best pens for colouring. There are always variables and options, based on your paper of choice, the amount of space you are covering, and your overall preference in a pen. Take some time to test out some open stock pens and see if you really like them before you invest in an expensive set. Once you find the best pen for coloring your preferred art, you will be so happy you took the time to research the best pen.

They are great for what I use them for, which is just coloring and drawing. The range of colors is fantastic, and they seem to be lasting pretty well (I’ve had them for about 6-1/2 months). I would deduct 1/2 star for the quality of the nylon tips…some of my markers that I use the most frequently have gotten to be very fuzzy at the end, which is most disappointing.
What to Look for When Buying Markers for Adult Coloring Books
Here’s what you should look for when searching for the best pens and markers to color with.
Pens may be water-based, alcohol, gel, or hybrid inks. Some pen types work better with certain paper types than others. Make sure to test different pens before using them on a project (especially if the ink is light) as some pens will smudge.
So, what types of pens are considered the best pens for coloring books? In general, gel and alcohol-based pens work well with very fine details and smooth coverage on your page. You can also blend colors from one color family to another with these pen types.
Water-based pens and markers lay down well and can be used on both sides of a page, but you might find that they don’t blend as well. They may also have a tendency to make your paper pull up or pill when the paper gets oversaturated.
These types of pens are water-soluble, so they’re great for coloring books with double-sided pages (just remember to test the pen first). Water-based pens don’t contain hazardous materials like alcohol or shellac.
Alcohol-based pens cover larger areas well and blend easily. They will dry quickly, they blend beautifully, and they are great for creating shading. If you want the best art pens for coloring books, alcohol-based is your go-to.
The only drawback to alcohol-based coloring is that it will bleed into the paper. This is what enables the inks to blend so well. But it makes it so you will not be able to color on pages that are printed double-sided without ruining one side.
Almost all gel pens are water-resistant once they have dried on the page–a great choice for double-sided coloring pages! Gel pens lay down opaque color on most types of paper, including non-porous materials like glossy pictures/photos/paintings that don’t absorb ink well. However, some colorists find that gel pen ink can be slow to dry on certain papers or on top of certain inks (for example, on glossy black paper).
Gel pens come in a wide variety of tip widths. If you want to get the best pen for coloring books, look for thicker-tipped gel pens over .3mm or .5mm–too thin and they can tear through some types of paper. Gel pens are some of the best drawing pens for adults because they lay down smooth color with little to no drag while writing on most types of paper.
Hybrid ink is made up of pigments suspended in water or oil–this type of pen lays down color very smoothly and can cover large spaces without bleeding through your pages. You will need fixative if you’re using Hybrid inks for your coloring books.
Sharpie(R) Permanent Markers:
That’s right–our beloved Sharpie is one of the best pens for drawing and coloring. They’re available in a wide variety of tip sizes, they don’t bleed through paper, they blend together very well, and they dry quickly without smearing. Just make sure you get an alcohol-based permanent marker rather than their water-based ones!
Other Important Factors to Consider when buying coloring pens
Price: Pens for coloring books can cost anywhere from $1/pack to more than $30/pack. Typically, pens designed specifically for art tend to be pricier (quality matters).
Permanence: Pens with erasable ink are also on the market. Sometimes after you’ve finished your project, you may want to go back and make corrections. These pens allow you to do exactly that!
Packaging: Consider packaging when buying markers for your adult coloring books–you don’t want to accidentally buy something that will dry out before you have a chance to use it all up! Pen sets are great because they aren’t exposed to air as much, so they tend to last longer.
Ease of use: Rather than trying out every pen on the market, look for the best pen for adult coloring books that matches your needs. Different materials will work better with different pens–that’s normal! Just pick the one that yields the results you’re looking for in terms of color quality and ease of application when using it on your coloring book pages.
Your likes and dislikes: Finally, consider your preferences when shopping for a marker or pen to use with your next adult coloring book project. For instance, if you have a specific color family that you prefer not to mix yourself (like reds or blues), buy a set that has those colors so you’ll be prepared for any coloring book page that comes your way. You can also consider how easy the pens are to hold and apply pressure with.
Type of paper: The best pens for adult coloring books will behave differently on different types of paper. Consider the absorbency factor of the type of paper you’re buying when buying coloring pens. If you like to color on thinner paper or print on both sides of your pages, you won’t want to use an alcohol-based pen or marker.
Paper weight: If you like heavier paper like card stock or watercolor, make sure that the marker or pen you choose doesn’t bleed through (some do). Some pens and markers, such as alcohol-based Sharpies, are more likely to bleed through the paper because they’re specifically made to lay down thick lines–so keep that in mind when shopping. If you like working on midweight papers (like printer or sketching paper), wide-tipped pens can be easier to work with.
Coloring book size: Consider the size of your coloring book pages when looking for pens and markers. Wide-tipped pens can be better than thin ones for covering bigger spaces–especially if you don’t want to spend a lot of time refilling/reloading your pen with ink during your color session!
Time constraints: How much time do you have to color? Pens that dry quickly are especially useful if you have time constraints on your coloring projects. Alcohol-based pens tend to be the fastest drying. Gel pens take a long time to dry and you won’t be able to work on your coloring if there is a large section that you might drag your hand through.
Resolution/detail needed: If you want the best pen for adult coloring books, consider how much detail you need on each page. Gel pens are great for drawing fine details, but only alcohol-based markers will lay down thick lines perfect for filling in large areas of color. Think about what types of images patterns you’ll want to color in your pages when choosing pens.
